Allseas, a global leader in offshore pipeline installation, heavy lift and subsea construction, has chosen WFS Technologies’ new Seatooth® Pipelogger for the real time measurement of process temperature on a subsea pipeline system which they have installed recently. The pipeline system is designed to have a total gas throughput capacity of 31.5 billion cubic meters per year.

WFS Technologies’ Pipelogger is a real-time, wireless technology which requires little to no maintenance, and can operate at depths of up to 2,000m without the need for periodic and costly ROV inspection - contributing significantly towards reducing the operating cost while monitoring process condition to optimize gas delivery parameters.

The new Mark III generation of Pipeloggers feature a hot-swappable sensor configuration as well as the capability to create subsea cloud networks for real-time analytics at the edge.

WFS Technologies is an industry pioneer of the Subsea Internet of Things (SIoT) devices.

Moray Melhuish, Commercial Director at WFS Technologies, said: “It is a great testimony of our SIoT tools that Allseas has asked us to embark on this new project with them for the delivery of our latest generation of Seatooth device.

“By combining our proven Seatooth technology with the ability to hot-swap components, we are able to future proof the installation by enabling the simple addition of capability as the requirement emerges. This can include ultrasonic flow, vibration, cathodic protection status, ultrasonic thickness and met ocean conditions, as well as the initial requirement – in this case, the monitoring of process temperature.”

Marcel van Schie, Assistant Project Manager at Allseas, said: “We selected WFS for their unique track record of supplying wireless subsea devices to meet demanding customer specifications. The adoption of this technology is consistent with Allseas goal to use innovative technology to meet the market’s ever-changing needs.”

The Seatooth® PipeLogger is a smart, wireless, subsea internet of things device designed to deploy multiple sensors and devices on subsea pipelines, trees, risers and manifolds. It is a cost-effective alternative to hard wired systems for production, flow and asset integrity monitoring and calibration. WFS’ patented Seatooth technology supports two-way communications through seawater, seabed, concrete coating, ice and the splash zone.
